I'm wanting to upgrade my HPUX Oracle 9.2.0.3 ORACLE_HOME to 9.2.0.5 but when I run the OUI (version 10.1.0.2) it doesn't find the ORACLE_HOME and lists the database install under 'Independant Products'.

Is there anyway of reinstating the ORACLE_HOME information into the oraInventory files (I believe OracleHomes.ser is where OUI gets the info from)?

Or will I have to uninstall / reinstall the base product ?
